Stainless Steel Phillips Flat Head Drilling Screws
 |
These corrosion-resistant screws drill and fasten in one step to secure trim, brackets, and other objects with countersunk holes. They have a flat, beveled head to sit flush with surfaces. The Phillips drive withstands less torque than a hex drive, so drill with even, steady pressure.
Length is measured from the top of the head.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.

Stainless Steel Square Drive Rounded Head Drilling Screws
 |
Drill and fasten in one step with screws that prevent drivers from slipping out. Also known as Robertson drive, the square recess withstands more torque than a Phillips drive. These screws resist corrosion and have a rounded head for a finished look.
Length is measured from under the head.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.

Sealing Stainless Steel Flanged Hex Head Drilling Screws with Washer
 |
These corrosion-resistant screws drill, drive, and create a watertight seal all in one shot. The rubber-bonded washer compresses to keep out moisture and spreads the load to prevent crushing thin metal. Use a nutdriver or socket to turn the hex head.
Length is measured from under the head.
Zinc-Plated 410 Stainless Steel—With a layer of zinc for added corrosion resistance, these screws are tougher and more wear resistant than other stainless steel screws.

Tamper-Resistant Torx Stainless Steel Rounded Head Drilling Screws
 |
Removable only with a tamper-resistant Torx driver, these screws drill and fasten in one step. The deep, six-lobe recess (also known as pin-in-Torx) prevents drivers from slipping and deters unauthorized access. These screws resist corrosion and have a rounded head to create a finished look.
Length is measured from under the head.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.
